Connect the PTX10001-36MR to Power

Connect the PTX10001-36MR to Ground

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the PTX10001-36MR chassis to connect to the earth ground.

Note:

An AC-powered PTX10001-36MR gains additional grounding when you plug the power supply into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX10001-36MR Power System.
CAUTION:

Before you connect power to the PTX10001-36MR, a licensed electrician must attach a cable lug to the grounding cables and power cables that you supply. A cable with an incorrectly attached lug can damage the PTX10001-36MR (for example, by causing a short circuit).
Note:

Mount your device in the rack before attaching the grounding lug to the switch. See Unpack and Mount the PTX10001-36MR.
Note:

You must install the PTX10001-36MR in a restricted-access location and ensure that the chassis is always properly grounded. The PTX10001-36MR has a two-hole protective grounding terminal provided on the chassis. See Figure 1. We recommend that you use this protective grounding terminal as the preferred method for grounding the chassis regardless of the power supply configuration. However, if additional grounding methods are available, you can also use those methods. For example, you can use the grounding wire in the AC power cord or use the grounding terminal or lug on a DC power supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

Ensure that you have the following parts and tools available (none are provided):

  • Grounding cable—The grounding cable must be 8 AWG (8.4 mm²), minimum 90° C wire, or as permitted by the local code.

  • Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD6-14AH-L or equivalent.

  • Two M6 x 10 mm screws and washers.

  • Screwdriver appropriate for the M6 x 10 mm screws.

To connect a grounding cable to the PTX10001-36MR:

  1. Attach a grounding cable to earth ground (such as the rack in which the PTX10001-36MR is mounted) and then attach it to the chassis grounding point. Figure 1 shows the location of the chassis grounding point.
    Figure 1: PTX10001-36MR Grounding PointsPTX10001-36MR Grounding Points
  2. Secure the grounding lug to the protective earthing terminal with the washers and screws. See Figure 2.
    Figure 2: Connect a Grounding Cable to a PTX10001-36MR DeviceConnect a Grounding Cable to a PTX10001-36MR Device
  3. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.

Connect AC/HVDC Power to the PTX10001-36MR

Before you begin connecting AC/HVDC power to the PTX10001-36MR:

The power supplies automatically detect whether there is AC or HVDC input voltage and manage the power accordingly. Each 3000 W AC/HVDC power supply module has a single AC or HVDC input and provides 12 V of power to the system. The power supply in a PTX10001-36MR is a hot-removable and hot-insertable field-replaceable unit (FRU). After removing the power cord from an individual power supply, you can remove and replace it without powering off the router or disrupting router functions.

CAUTION:

Do not mix AC/HVDC and DC power supplies in the same chassis.

Note:

Each power supply must be connected to a dedicated power source outlet.

To connect AC power to a PTX10001-36MR:

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Locate the power cord or cords shipped with the PTX10001-36MR; the cords have plugs appropriate for your geographical location. See Table 4.
    Warning:

    Ensure that the power cord does not block access to router components or drape where people could trip on it.

  4. Connect each power supply to the power sources. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate (see Figure 3).
    Note:

    The coupler end of the power cord model is APP-400.

    Figure 3: Connect an AC Power Cord to the PTX10001-36MR Connect an AC Power Cord to the PTX10001-36MR
  5. If the AC power source outlet has a power switch, set it to the off (O) position.
    Note:

    The device powers on as soon as power is provided to the power supply. There is no power switch on the device.

  6. Insert the power cord plug into an AC power source outlet.
  7. If the AC power source outlet has a power switch, set it to the on (|) position.
  8. Verify that the status LEDs on each power supply are lit green.

    If the status LED is lit amber, remove power from the power supply, and replace the power supply (see Maintain the PTX10001-36MR Power Supplies). Do not remove the power supply until you have a replacement power supply ready.

    CAUTION:

    Replace a failed power supply with a new power supply within 2 minutes of removal to prevent chassis overheating.

Connect DC Power to the PTX10001-36MR

Before you begin connecting DC power to the PTX10001-36MR:

The DC power supply in a PTX10001-36MR is a hot-removable and hot-insertable field-replaceable unit. You can remove and replace it without powering off the router or disrupting router functions. You do, however, need to remove power from the power supply before attempting to remove the unit.

Warning:

A DC-powered PTX10001-36MR is intended for installation only in a restricted-access location.

CAUTION:

Do not mix AC and DC power supplies in the same chassis.

Note:

Each power supply must be connected to a dedicated power source outlet.

To connect DC power to a PTX10001-36MR:

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Depending on the input power source, set the DC input current selector (DIP switch) to 80 A or 60 A.

    Figure 4 shows the location of the DC input current selector (sometimes called the DIP switch).
